Perhaps you don't want any media wiki discussions any more. One solution: Create a Subforum (e.g. "Wiki Articles") and link to this forum instead to the wiki discussion page:
in vbMediaWiki.php search for

                    echo'><a href="'.htmlspecialchars($tab['href']).'"';

and replace with

                    if ($key != "talk") {
                        echo'><a  href="'.htmlspecialchars($tab['href']).'"';
                    } else {
                        echo'><a  href="/forum/forums/69-Wiki-Artikel"';
                    }

replacing the bold part with the correct link for your forum.

The same way you can remove the user discussion: In vbMediaWiki.php search for

        foreach($this->data['personal_urls'] as $key => $item) { ?>
            <li><a href="<?php echo htmlspecialchars($item['href']) ?>"><?php echo htmlspecialchars($item['text']) ?></a></li><?php
        }

and replace with

        foreach($this->data['personal_urls'] as $key => $item) { 
            if ($key != "anontalk" && $key != "mytalk") { ?>
                <li><a href="<?php echo htmlspecialchars($item['href']) ?>"><?php echo htmlspecialchars($item['text']) ?></a></li><?php
            }
        }

Example
